First, What version are you on? This update is intended for 19043 21H1 Beta. So technically (i haven't done it) you should at least be on 19043.599.
Do you have CAB install in your context menu?
Brink has a great tutorial to use cab install HERE
If you aren't on 19043.599, you need to use 21H1 Enablement package windows10.0-kb5000736-x64.cab
I'm on 19043.899 Beta channel, I got the Feature experience update but the cumulative update fails to install
